This invention relates to a tamping device pivotally supports a pair of tamping blades particularly adapted for use upon the road 11. Each of the blades 11 consists of ametal beds of railways to tamp beneath and at the plate of substantial width and sufiicient sides of the ties. rigidity to maintain its bent form. The
5 It is my object to provide an attachment for blades 11 have pivot bearings upon a pair of 55 a tamping machine which is designed to operrods 12. Arcuate central portions of the ate more rapidly and efliciently to tamp the rods 12 engage the sleeve between a pair of road bed at both sides and beneath atie simulflanges 13 and the ends of the rods 12 protaneously while avoiding lateral displaceject at the side edges of the blades 11 and 10 ment of the tie. ther objects will appear are connected together by a pair of cross to and be more fully pointed out in the followmembers 14, as best shown in Figs. 3 and 4. ing specification and claims. Above the rods 12 the blades 11 are bent out- In my Patent No. 1,684,109, dated Septemwardly to form arms 15, the upper ends of ber 11, 1928, I have described and claimed a which are joined by toggle members 16 to machine for tamping the road bed between a sleeve 17 fixed on the shaft 8. Rigid reinc5 ties and the present invention may be used forcing members 11 extend obliquely be to advantage with the machine of that patent. tween the arms 15 and outer extremities of the Many of the tamping machines heretofore blades 11, being fixed at their upper ends on provided tamp the road bed only between the arms 15 and at their lower or outerends 2o es nd Such machines often shift the ties upon the blades 11. Confined between the 70 laterally out of proper position and leave bottom of the sleeve 17 and upper flange 13 the material beneath the ties in loose, unon the sleeve 10 is a coiled spring 18, adapted tamped condition. The present invention 18 to normally supportthe tamping blades 11 designed to overcome these difficulties and to in the elevated or retracted position shown perform mechanical tamping which resembles in Fig. 2. Beneath the lower'flange 13 and 75 the'manual tamping where two men work secured to the sleeve 10 is a second coiled simultaneously at opposite sides of each tie, spring 19 of somewhat stiffer construction driving the tamping tools beneath the ties. th th s ri 18; A h 201 f t d to In the accompanying drawings which illusthe lower end of the spring 19 to engage the t ate t e be form o y d vi e at p sent upper surfaceof the tie 21 adjacent to and be- 80 known to me, Figure 1 is a side eleva i n 0f neath which the road bed 22 is to be tamped. the invention attached to a tamping machine A illustrated, I have shown my invention of the yp described 111 y b identified in connection with the tamping machine 9 patent; Fig. 2 is an enlarged C n r veltlctll supported upon rails 23 which are mounted section through the device detached. from the i th usual manner upon th ti 21 Thi 85 machine and showing its relation to a rail and hi 9 h a Poweld -i h ft 2% P i s as in p i 8 g l ating an eccentric wheel 25.

I '{lhe on the line of pivo snlai lnay ellillSC anc owelec to An upright shaft 8 is arranged to be given adlust t helg 'd Shaft y 95 vertical reciprocatingmovement by a suitable 1 as the {nachlne 9 y power driven machine 9, the machine illusflbOVe l'dentlfied P A sultilble gu1fle30 trated being like that described in my Patent 1S p l l 1 0 t e S a t 8- It Wlll be evident No. 1,684,109. The lower end of the shaft 8 that a number of the ta-mplng shafts 8 with is slidable longitudinally in asleeve 10 which associated operating and tamping mecha- 109 of the tamping blades; Fig.6 is a detail, side view of a suitable supporting sleeve for the nisms, may be provided upon the machine 9 as in the machine of my prior patent.
Operation In operation, when the road bed 22, adjacent to and beneath a tie 21, is to be tamped, the machine 9 is moved to a position where the shoe or shoes are above the tie 21 and then the pivot shaft 28 is raised so as to lower the shoe 20 into contact with the tie. The tamping blades 11, which are normally in the elevated position shown in Fig. 2, are now placed in operation by rotating the shaft This, through the eccentric wheel 25 and band 26, imparts oscillating movement to the arm 27 and vertical reciprocating movement to the shaft 8. As the shaft 8 starts downward,
the sleeve 10 is held against movement by the spring 19 and shoe 20 resting upon the tie 21 so that the lower end of the shaft moves downward within the sleeve. stroke the spring 18 is compressed and the toggle members 16 are actuated to pivot the blades 11 on the rods 12. The operating edges of the blades are thus thrust downward and toward each other, passing beneath the tie 21 at opposite longitudinal sides thereof. hen the blades have reached their inner extremity of movement and upon the return stroke of the shaft 8, the spring 18 operates to withdraw the blades 11 from a position like that indicated in Fig. 1 and to return them to retracted position, shown in Fig. 2. The operation is repeated upon the next downward stroke.
In this manner it will be evident that the road bed is simultaneously tamped at both longitudinal sides and beneath the tie upon each downward thrust of the shaft 8. There is no tendency to move the tie and it is held and the position of the tamping members determined by the shoe 2O engaging the upper surface of the tie. The spring 19 operates to compensate for any irregularities and nonuniformities in the ties. It also relieves possible excessive strains on the mechanism and allows the sleeve 10 to move downward in the event that a blade 11 strlkes an immovable fobstacle during the tamping stroke. The tamping with my machine closely resembles in thoroughness the best manual work which has heretofore been performed by pairs of men simultaneously tamping along opposite sides and beneath each tie.
Having described my invention, what I claim as new and desire to protect by Letters Patent, is:
